Product Description

Vortioxetine lactate (formerly Lu-AA21004 lactate; Trintellix; Brintellix) is the lactate salt of Vortioxetine, which is an atypical antidepressant which was approved in 2013 by the FDA for the treatment of major depressive disorder (MDD) in adults. It has IC50 values of 15 nM, 33 nM, 3.7 nM, 19 nM, and 1.6 nM for 5-HT1A, 5-HT1B, 5-HT3A, 5-HT7 receptor, and SERT, respectively.

Biological Activity I Assay Protocols (From Reference)
ln Vitro

In vitro activity: Lu-AA21004 suppresses recombinant human CYP1A2, CYP2C9, CYP2D6, and CYP3A4 with IC50 of 40 μM, 39 μM, 9.8 μM and 10 μM, respectively. Lu AA21004 is a partial h5-HT1B receptor agonist that exhibits a whole-cell cAMP-based assay EC50 of 460 nM and intrinsic activity of 22%. In vitro whole-cell cAMP assay, Lu AA21004 binds to the r5-HT7 receptor with a Ki value of 200 nM and is a functional antagonist at the r5-HT7 receptor with an IC50 of 2 μM.

ln Vivo
Lu-AA21004 in rats has been found to have hepatic clearances of 7.1 (L/h)/kg and oral bioavailabilities of 16%. Extracellular 5-HT levels in the ventral hippocampus of conscious rats are elevated by Lu-AA21004 (2.5 mg/kg, 5 mg/kg, or 10 mg/kg sc). In the medial prefrontal cortex (mPFC), after three days of treatment, basal levels of 5-HT are also significantly higher when administered at 5 mg/kg or 10 mg/kg sc with Lu-AA21004. After administration of 5 mg/kg or 10 mg/kg for three days, Lu-AA21004 occupies 43% and 57% of SERT in the medial prefrontal cortex of rats. An hour after subcutaneous administration, rats treated with Lu AA21004 showed dose-dependent occupancy of the 5-HT1B receptor and the SERT, with ED50 values of 3.2 mg/kg and 0.4 mg/kg on rats. Lu AA21004 inhibits transient bradycardia in rats by affecting the Bezold-Jarisch reflex in a dose-dependent manner (ED50 = 0.11 mg/kg). Rats' medial prefrontal cortex and ventral hippocampus have higher extracellular levels of 5-HT, DA, and NA when exposed to Lu AA21004 (2.5–10.0 mg/kg s.c.). Rats with 41% occupancy at the SERT showed an increase in the extracellular levels of 5-HT (200%) in the ventral hippocampus when exposed to Lu AA21004 (5 mg/kg s.c.). The immobility duration is considerably shortened in the FSL rats by Lu AA21004 (7.8 mg/kg s.c.), but not in the FRL rats. Rats' conditioned fear assay: dependent anxiolytic-like effect. In male Sprague-Dawley rats, vortioxetine (10 mg/kg) significantly increases freezing 60 min prior to acquisition, suggesting enhanced formation of contextual memory during acquisition and/or consolidation. Moreover, increased freezing rates during retention are caused by vortioxetine (5 mg/kg); post hoc tests revealed that this effect was statistically significant. Prior to acquisition, vortioxetine (2.5 mg/kg or 5 mg/kg) exhibits average exploration times for the novel object of 29 and 33 seconds, respectively. In rats, nociception is markedly reduced by vortioxetine (10 mg/kg), as evidenced by increased paw withdrawal latency. Twenty minutes after injection, the levels of ACh are raised to 224% and 204% of baseline by vortioxetine at doses of 5 and 10 mg/kg.
Enzyme Assay
Vortioxetine (Compound 5m) is a multimodal serotonergic agent that inhibits SERT with values of 1.6 nM, 33 nM, 3.7 nM, 19 nM, and 5-HT1A, 5-HT1B, and 5-HT7 receptors, respectively. Vortioxetine exhibits strong suppression of SERT as well as antagonistic effects at 5-HT3A and 5-HT7 receptors, partial agonist effects at 5-HT1B receptors, and agonistic effects at 5-HT1A receptors.
Cell Assay
Vortioxetine is a partial h5-HT1B receptor agonist that, in a whole-cell cAMP-based assay, has an EC50 of 460 nM and an intrinsic activity of 22%. In vitro whole-cell cAMP assay, vortioxetine binds to the r5-HT7 receptor with a Kivalue of 200 nM and is a functional antagonist at the r5-HT7 receptor with an IC50 of 2 μM.

Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
